Introduction
Congratulations on your purchase of an Expert Sleepers “Pandora”. Please read this user manual
before operating your new module.
Pandora is a bandpass flter/distortion processor, based on an unusual combination of power
MOSFET transistors and vactrols. Voltage control is provided over the two sides of the flter, the
gain, and the flter feedback. A wet/dry mixer is provided, also under voltage control.
A range switch is provided to drop the flter response several octaves, at which point the module
becomes capable of synthesising percussion sounds when fed trigger pulses.
The module is 100% analogue.
Installation
House the module in a Eurorack case of your choosing. The power connector is 16-pin
. If using the power cable supplied with the module, the red edge of the cable is closest
to the bottom edge of the PCB, and carries -12V. ("-12V" is marked on the PCB itself next to this
end of the connector.) Be sure to connect the other end of the power cable correctly, again so
-12V corresponds to the red stripe on the cable.
Power requirements
Pandora draws up to 69mA on the
+
12V rail, and 58mA on the -12V rail.
It does not use the 5V rail.
